When integration with Graphus is enabled, all users/ targets in an organization should be Microsoft licensed users which can be viewed on the following location: https://cloud.graph.us/orgUsersLicense?licenseType=protected
Emails will not be delivered to unlicensed Microsoft users. BullPhish ID campaign emails will only be delivered to licensed Microsoft users.
BullPhish ID team is working on a solution to automatically inactive organizations with unlicensed users. This is to ensure that MSPs can continue sending their campaigns through SMTP service where whitelisting is required. This info is also available in our setup guides. https://helpdesk.kaseya.com/hc/en-gb/articles/6937751190289-06-30-2022-How-to-Enable-Integration-with-Graphus
